The Hall of Nations and the Hall of Industries make up the industrial exhibition complex. The Hall of Industries consists of four space-frame structures each spanning 144 feet. The Hall of Nations is a single space frame with a clear span of 256 feet. The buildings are linked together at their mezzanine levels by a series of circulation ramps that enclose an outdoor exhibition area. The building and sanitary services are housed under the ramps.
